Authentication Clock Skew | Playbook Use Case KB Number: KB0639127 

 

Overview

The number in seconds before notBefore constraint, or after notOnOrAfter constraint, to consider whether it is still valid. Update the SAML property glide.authenticate.sso.saml2.clockskew to a larger value with a default of 60 seconds. Some cases require a setting of 300 or higher. If the identity provider server is connected to a time sync server its time should not be out of sync. The customer’s network team will need to resolve this issue.

PORTUGUÊS

Os segundos antes de notBefore constraint, ou depois notOnOrAfter constraint, para considerar se ainda é válido. Atualize a propriedade SAML glide.authenticate.sso.saml2.clockskew para um valor maior com um padrão de 60 segundos.

Alguns casos exigem uma configuração de 300 ou superior. Se o servidor do provedor de identidade estiver conectado a um servidor de sincronização de horário, seu horário não deverá estar fora de sincronia. A equipe de rede do cliente precisará resolver esse problema.
